## Abstract The readily available alkyl dicyanoacetates 1 reacted with the 1,3โdipolar reagents arenecarbonitrile oxides 2โฒ and arenecarbonitrile imines 5โฒ to afford 1,2,4โoxadiazol and 1,2,4โtriazol derivatives. The arenecarbonitrile oxides 2โฒ with electronโdonating groups on the arene ring gave p
Chiral non racemic carbazate 1, derived from (R)-(-)-phenylglycinol, reacts regioselectively with benzaldehyde or its dimethylacetal to give an azomethine imine. The faci~d, endo/exo and regio selectivities of 1,3-dipolar cycloadditions of this reactive species with various dipolarophiles have been
